AllsurfacesemitinfraredradiationTheintensityofthisinfrared
radiationchangesaccordingtothetemperatureoftheobject.
Dependingonthematerialandsurfaceproperties,theemitted
radiationliesinawavelengthspectrumofapproximately1to20μm.
Theintensityoftheinfraredradiation(”heatradiation”)isdependent
onthematerial.Formanysubstancesthismaterial‐dependent
constantisknown.Thisconstantisreferredtoasthe”emissivity
value”.
Infraredthermometersareoptical‐electronicsensors.Thesesensors
aresensitivetotheemittedradiation.Infraredthermometersare
madeupofalens,aspectralfilter,asensor,andanelectronicsignal
processingunit.Thetaskofthespectralfilteristoselectthe
wavelengthspectrumofinterest.Thesensorconvertstheinfrared
radiationintoanelectricalsignal.Thesignalprocessingelectronics
analyzetheelectricalsignalsandconvertitintoatemperature

dependentonthematerial,therequiredemissivitycanbeselectedon
thesensor.
Thebiggestadvantageoftheinfraredthermometerisitsabilityto
measuretemperaturewithouttouchinganobject.Consequently,
surfacetemperaturesofmovingorhardtoreachobjectscaneasilybe
